The project's objective

The objective was to design a new 420 kV overhead transmission line tower that had to comply with predefined requirements set forth by Statnett. The work involved concept design, architectural design, structural design, electromechanical design, cost estimation and 3D visualisations of the proposals.

The winning proposal is named the STRAW, while SENTINEL ("Spire" in Norwegian) was awarded second place. Engineers from EFLA prepared the new concepts in collaboration with Eva Widenoja, an industrial designer from Widenoja Design AS.

The new transmission line will replace an older 300 kV line and will be seen by a large number of people every day, thus making it important to blend well with its environment.

Environmental issues

Steadily growing environmental awareness and the importance of preserving nature has led to a stronger emphasis on adapting new transmission line structures to their immediate surroundings and the landscape. The STRAW adapts well to its surroundings and is more environmentally friendly than today's standard towers with regards to electro-magnetic fields and footprint.
